}}Tillegra Dam was a proposed dam on the Williams River to be located {{Convert|20|km|mi|0|abbr=on}} northwest of Dungog, in the Hunter Region of New South Wales, Australia. It was first proposed in the 1970s but a formal proposal was not announced until 2006. Community opposition and changing needs saw the end of the proposal in November 2010. Hunter Water Corporation divested itself of its Tillegra landholding in 2015, permanently ending the proposal.[1]

Overview

The Tillegra Dam was first proposed by the Hunter Water Corporation in the 1970s, but was deferred indefinitely in the 1980s due to the success of user pays pricing.[2] On 13 November 2006, the NSW Government announced proposals for a A$300 million dam at Tillegra to supply water to the Lower Hunter Region and Central Coast. The justification for the dam was based primarily on climate change and population growth in the Hunter Region.[3]

Opposition

The No Tillegra Dam Group was formed to prevent the building of the dam. Opponents claimed the dam proposal was grossly excessive for need, will drown valuable agricultural land and greater water efficiency, demand management and recycling would eliminate the need for the dam.[4]

Cancellation

On 28 November 2010 then NSW Premier, Kristina Keneally, announced the cancellation of the dam after the Planning Minister refused to approve it.[5] The refusal was based on both the potential for environmental damage and the lack of proper consideration of alternative water security measures.[6] The state government had already spent $100 million on the project.
